(i don't know how to name this) mod problem :-(

I have exported my own cars. When i spawned them in BeamNG.drive, they become white with red lights. What is going on?

P.S. Also BeamNG.drive doesn’t see colors in the mod car.

P.P.S. On some cars, the “Fatal vehicle expectation” shows.

Automation: 210706.15597.56.Manual

BeamNG.drive: v0.
